PROBLEM TO BE SOLVED: To enable nonmetallizing, fire retardance, excellent handling and a lower cost by housing an optical fiber into double pipes made of plastic and mounting optical connectors at its terminals. SOLUTION: The optical fiber cable with connectors is produced by housing the optical fiber 11 in the state of including its extra lengths into the inside pipe 10 made of plastic, inserting this inside pipe 10 into the outside pipe 12 made of plastic and mounting the optical connectors 13 having ferrules 15 at both terminals. The inside pipe 10 is preferably composed of a cylindrical pipe having a smooth surface and the outside pipe 12 of a grooved pipe structure of a bore in proximity to the outside surface of the inside pipe. As a result, the outside pipe 12 acts as a guide to substantially prevent the occurrence of buckling in the inside pipe 10 and to make the handling easy and excellent when the double pipes are bent over the entire part. When the double pipes 14 are crushed by abnormal compressive force, the inside pipe 10 acts as a buffer to provide an effect of preventing the direct damage on the fiber 11. Since the materials are the plastic, the damage on the optical fiber 11 hardly arises.
